Description

  The present invention relates to a medical aspirator for aspirating a patient's body fluid and secretions, and more particularly to a medical aspirator adapted to be used for home medical treatment.

  In medical institutions such as hospitals and clinics, various types of medical suction devices are installed in operating rooms and sick rooms. For example, a medical suction device provided in an operating room is configured to be able to agitate and coagulate physiological fluid or the like used for washing an affected part or a body fluid containing blood generated during surgery. In addition, a medical aspirator provided in a patient's room is configured to be able to aspirate and coagulate a patient's secretion including sputum.

  Medical aspirators used in medical institutions are bottles that are kept airtight by covering a lid and store aspirated body fluid, secretions, etc., and a bottle holder that detachably attaches and holds the bottle It is common to be configured to have a body. And while applying suction pressure to the inside of a bottle and applying a patient hose attached to a lid to an affected part, it is constituted so that a bodily fluid and a secretion can be sucked and stored in a bottle. In such a medical suction device, a storage bag is provided inside the bottle, and the body fluid or secretion sucked through a patient hose is stored in the storage bag and coagulated, and the solidified storage bag is discarded It is generally configured to be disposable.

  In the portable medical suction device, the suction pump is driven by a direct current motor and rotates at a fixed number of rotations corresponding to the voltage applied to the motor. Then, by adjusting the opening degree of the needle valve, the suction flow rate is adjusted, and a suction pressure corresponding to the adjusted suction flow rate is generated. That is, the suction pump is set to rotate at a rotational speed that can achieve the maximum suction flow rate required for the medical suction device, and when the needle pump is opened while the suction pump is operating, the needle valve is opened. A suction pressure is generated that achieves a suction flow rate depending on the degree. The suction pressure is displayed on the pressure gauge and acts on the bottle, and by applying a patient hose connected to the bottle to the affected area, it is possible to suction body fluid and secretions.

  In the conventional portable medical suction device, the rotation speed of the suction pump is constant, and the suction flow rate and the suction pressure are substantially in direct proportion to the opening degree of the needle valve. That is, the suction flow rate and the suction pressure can not be adjusted independently of each other, and the suction pressure can be increased by opening the needle valve to increase the suction flow rate. However, in the affected area where it is necessary to aspirate body fluid and secretion, there is a site where it is not preferable to apply a large suction pressure while requiring a large flow rate, and it is difficult to apply to such an affected area. There is a risk of

  An object of the present invention is to provide a medical aspirator that can be used for home medical care, in which the suction pressure applied to the affected area and the suction flow rate can be adjusted independently of each other.

The bottle member D used in the present embodiment is different from the above-mentioned bottle member C in the structure of the connecting portion with the suction pipe. However, the main body A and the filter member B are configured such that those described in the above-mentioned embodiments can be used as they are.

  The bottle member D in the present embodiment is provided on the wall of a hospital room or medical office in a medical institution, and attached to an outlet having a mounting member to which a pipe for suction is connected and to which the bottle member D is attached and detached. It is configured to be usable. For this reason, the bottle body 51 has a height larger than the height of the main body A. In such a bottle member D, the volume of the bottle body 51 is large, generally about 4 liters, and the weight also increases. Like the above-described bottle body 41, the bottle body 51 is configured as a cylindrical transparent container, and a scale not shown is formed on the side surface.

  A pair of rails 52a is formed on the upper surface of the lid 52 constituting the bottle member D, and a vent hole (not shown) for ventilating the bottle body 51 is formed between the rails 52a. The bottle member D is configured to be attachable to and detachable from an outlet provided in the patient's room via the rail 52a, and when installed at the outlet, the bottle member D is formed between the piping for suction provided in the outlet and the rail 52a. The vents are connected in an airtight manner.

  Further, a horn 52b is disposed at a substantially central portion of the lid 52 and between the pair of rails 52a, and when the suctioned material reaches the storage limit of the bottle body 51 by this horn 52b, an alarm is sounded. It is configured to be able to alert the surrounding people.

  Because the volume of the bottle body 51 is large, the weight is large. For this reason, a handle 51 b is provided on the bottle body 51 so as to facilitate disposal of the aspirated material contained in the bottle body 51 and an operation at the time of cleaning. The handle 51b is configured to be able to control the opening and closing of the lid 52, and is closed by closing the lid 52, and pressing the opening and closing button 51c allows the lid 52 to be exposed to the bottle body 51. It is possible to release the lid state.

  Further, at a predetermined position on the upper surface of the lid 52, an attachment portion 53 for attaching a patient hose is formed. The mounting portion 53 is configured to penetrate the lid 52 in the thickness direction, and is formed in a hose shape in order to mount the patient hose.

  When the bottle member D configured as described above is attached to the main body A, it is necessary to transmit the suction pressure through the vent holes formed between the pair of rails 52a provided on the upper surface of the lid 52. Therefore, a bracket 54 is attached to the rail 52 a of the lid 52, and the bottle member D is connected to the suction pump 13 via the bracket 54 and the filter member B.

  The bracket 54 is formed in a U-shape and has a main body 54a closed at one end, and the sliding portion 54b provided on the main body 54a engages with the rail 52a of the lid 52 and slides. The cover 52 is configured to be removable. Further, a connection port 54c is provided to project from the closed end of the bracket 54, and a connection hose 55 is connected to the connection port 54c. Furthermore, a seal packing 54d is disposed on the inner side of the connection port 54c formed at the closed end of the bracket 54, and when the bracket 54 is attached to the lid 52 via the rail 52a, the seal packing 54d is configured to seal the air vents formed between the rails 52a to maintain air tightness.

  Moreover, when attaching the bottle member D to the main body A, it is necessary to hold the bottle body 51 in a stable state. Therefore, by holding the bottle body 51 on the bottle body holder 57 and mounting it on the main body A, the bottle body 51 can be stably held.

  The bottle holder 57 has a function of holding the outer periphery of the bottle 51 of the bottle member D and attaching it to the main body A, and a function as a relay point for transmitting suction pressure between the bottle member D and the filter member B. It is a thing. For this reason, the bottle holder 57 comprises a holding member 57a, and a conducting member 57b which protrudes from the holding member 57a and relays the bracket 54 and the filter member B.

  The holding member 57a constituting the bottle holding body 57 has an inner diameter larger than the outer diameter of the bottle body 51 to be held, and is formed in an arc shape partially cut away. In particular, the holding member 57a is configured of a base portion having rigidity and a grip portion having an appropriate elasticity formed in a predetermined range on the cutout side. Therefore, it is possible to hold by inserting the bottle body 51 of the bottle member D into the holding member 57a from above. And, even if a lateral movement occurs in the held bottle body 51, it is possible to continue the stable holding state by the elasticity of the holding portion.

  The conduction member 57b is formed at the base of the holding member 57a. That is, a projection 57b2 constituting the conduction member 57b is formed at the base of the holding member 57a, and a connection port 57b1 connected to the connection hose 55 is formed in the projection 57b2. A vent hole penetrating from the connection port 57b1 through the inside of the projection 57b2 to the lower surface is formed, and a connection tube connected to the holder suction port 31a1 of the filter member B is attached to the lower surface.

  The connection tube, like the connection member 35 described above, is formed in a linear socket shape by, for example, silicone rubber having flexibility and elasticity. Then, one of the connection ports is attached by being inserted into a hose holder provided on the lower surface side of the conduction member 57b. The other end of the connection tube is formed such that the inner diameter of the opening is larger than the outer diameter of the holder suction port 31a1 so that the holder suction port 31a1 can be easily inserted. Therefore, when the holder suction port 31a1 is inserted into the connection tube, it is possible to reliably hold the inserted state.

  A procedure for constructing the aspirator by the body A, the filter member B, and the bottle member D configured as described above, or for separating it from the aspirator will be briefly described.
